Definitions

  • the invention relates to a spigot-and-socket conduit joint with an anchor structure, especially to a spigot-and-socket conduit joint with an anchor structure for a spheroidal graphite cast iron pipe.

  • the spigot-and-socket conduit joint with the anchor structure which is stopper (or the like) is popular to numerous users.
  • Such joint typically includes a socket and a spigot.
  • a spigot stopper ring is arranged in the spigot. After the spigot is inserted into the socket, a stopper is inserted through a stopper mounting groove. The disengaging of the spigot and the socket is prevented by anchoring the spigot in the socket by means of the stopper.
  • the stopper is the significant guarantee for the reliable connection of the joint. Once the stopper is dropped out, the connectivity of the joint is damaged even causing the spigot to be disengaged from the socket. Accordingly, how to avoid the disengaging of the stopper is a significant technical problem concerned by those skilled in the art.
